Of course I don't get to drive mine too much and have only had to fill up once since the new pump was installed.
Am curious as to what the final verdict will be after you replace your pump. Keep us posted.

Hey brotha, forgot to update this thread with the end result,
So after multiple tests, it’s safe to say I was definitely the fuel pump that was causing all the issues. Upon removing and replacing the DW pump with an exact replacement, come to find out I actually I lied and didn’t use the spacer as I originally said, and ended up finding 3 O-rings that looked like it got pinched and mutilated. The fuel pump was having a bad seal and sucking in air.
So I made sure to apply a liberal amount of the supplied grease, and after some test, all problems went away. Gas tank finally went below the 1/4 mark for the first time in over a year and even some more once the light came on, squeaking from the HPFP went away, no more lagging and stalling in stop and go traffic, and the strong stench of a bad A/F mixture from the exhaust went away. Starts up like a charm every time now and can hear the beautiful faint noise of a fuel pump running in the background for the warm and fuzzies haha.
So hopefully this helps any with trouble shooting with similar problems and want to thank everyone for the insight!
